To all 'whom it may concern: Be it known that I, ALFRED BENDLIN, acitizen of the United States, and resident of Milwaukee, in the countyofMilwaukee `feature, whereby to increase its range of usefulness andfacilitate its manipulation.

A more specific object of the invention is to provide improved meanswhereby the bracket may be adjusted in any direction throughout an arcof 360 and to provide easily manipulated means for locking the same inthe position to which it has been adjusted.

ln describing my invention, reference will be had to the accompanyingdrawings, which represents an elevational view of my invention withparts thereof shown in section.

The numeral 1 indicates a base block which may be secured to the Hoor orside wall or any other suitable support, by means of suitable fasteningdevices 2. Extending from the base block are a suitable number of hollowsections 3,' 4, 5, 6, and 7, which are secured to each other in series,by means of universal joints. Each of these joints preferably includesan outercup shaped member or socket 8, within which is mounted aspherical head 9, the latter being retained by a retaining flange 10,and a shoe 11 which may be adjusted bymeans of a screw 12 to exertgreater or less pressure upon the head 9.

The several sections may be made in any convenient form which provides asuitable range of adjustment. For exam le, the sections 5 and 6 may beangular in s ape, while the section 7 may be extensible and held in itsposition of adjustment by the setscrew 13 or the like.

l'he outer end of the bracket carries a suitable supporting block 14, towhich may secured any 4attachment with which the bracket is deslgned. to-be used. One of the section is -provided with a cylindrical portion 15,withinjwhich is reciprocably mounted ahead 16which 'is carried at'theend of a sprinlgl? which isfseated at its outer end on a ri orprojection 18. A pair of cords or cables 19 and 2O are secured at one'end to the head `16.` The first of these `cords passes' thru the hollowsections 7, 6, 5, 4 and the like, and is attached atgits other end tovthe base block 1. The othercord 20 passes Aaround suitable pins 21 V.and22,' and is se-l cured at its other` end at a point adjacent thesupporting block 14, as shown at'23.

A quadrant 24 is formed integral with, or secured to the cylinder 15,and a lever 25 is operatively connected therewith. A cordv 26 is securedat one end to the lever and( passes thru eyes 27 into the cylinder 15and is secured at its other end to the head 16.

4It will of course be obvious that any num-1 l. ber of adjustablesections may be connected j in the manner indicated, and that they mayWhen the bracket is inthe desired posi# tion of adjustment, the lever 25is swung out-1- wardly to draw the head 16 against the resistance of thespring 17. The cords19 and 20 will therefore-be dra-wn tight, and thelever may be locked by means of` the,

pawl and detent 28. The tensioning of the cords 19 and 20 will thusincrease the pres' sure between the different members of the universaljoints and the latter beheld in their adjusted position by friction. Any

looseness or play which may develop within up -by adjusting the v thejoints maybe taken shoes 11. j j l While I have shown and describedspeciically one structure by means of which my invention may becarriedout, it will be understood that various modifications may' bemade therein without departing from theprinciple of the invention. Forexample, magnetic means for controlling and ac 1::

ing the lever 25 may be used. The clifenet`A sections of the bracket maylalso be varied;

Nif` be easily manipulated so as to bring the j supporting block 14 intoany plane desired.
